CrossChexCloudAPI module for Anviz Biometric Integration

This module provides a wrapper for interacting with the CrossChex Cloud API to manage
authentication, attendance data retrieval, and token handling. It allows for secure
communication with the API, including fetching and validating tokens, and retrieving
attendance records .
